Byron's Bastiodon was Byron's main Pokémon.
When Roark challenged his father using his Rampardos, Byron used Bastiodon and the two Pokémon were evenly matched but Team Rocket interrupted before the battle could finish.
Bastiodon was the last Pokémon Byron used whilst battling Ash. It easily defeated Chimchar with Metal Burst and then battled Gliscor. Despite the fact that it was Gliscor's first Gym battle, Gliscor managed to hold its own against Bastiodon and finally defeated him with Fire Fang.
